Two problems we solve
Most engineering teams arrive here because of one of two situations. Both are solvable.
Problem 01
You need to call an app's API but there is no documentation
The app works. The data you need is inside it. But there is no public API, no maintained SDK, and no one at the vendor who will help you integrate.
We decompile the APK, trace the network traffic, and rebuild every API call — login, session, headers, tokens, and request signatures — as a working Postman collection or Python client.
APK to API serviceProblem 02
You need to rebuild a feature but the source code no longer exists
The feature still works in the old system. But the code is gone, the developer left, or the platform is being shut down. You need that behavior in your new stack before the window closes.
We study the working feature, map every state and rule, and deliver a clean implementation in your chosen language and architecture.
Feature to Code serviceWe work from what still runs
We do not need source code to start. We need the software to be running. That can be an APK, a live web app, a desktop application, a video walkthrough, a test account, an old binary, or a network capture. We observe the behavior, document it, and rebuild it.
What teams use this for
Integration without an SDK
Connect your product to a platform that works but has no public API, no documentation, and no developer support.
Source code recovery
Recover the business logic from a system where the code, documentation, or original engineers are no longer available.
Legacy migration
Move a workflow from an end-of-life platform into a modern stack before the old system goes offline.
Feature preservation
Keep the behavior users depend on while replacing the code, architecture, or vendor behind it.
Every delivery is tested against the original
We do not hand over a list of captured URLs or a rough implementation and walk away. The deliverable passes the same test the original software passes. We run the action in the APK and in your client. We run the feature in the reference app and in the new implementation. If the results do not match, the job is not finished.
- Every action or feature is listed before work starts.
- Each item has a clear input, an agreed output, and a test.
- The delivery follows your stack, your conventions, and your tooling.
- The setup guide shows your team how to install and run it on day one.
- You get the full source code with no ongoing dependency on us.
Choose by what you have and what you need
- Have an APK and need to call its API from your own code? APK to API is the right service.
- Have a working feature that needs to exist in your codebase? Feature to Code is the right service.
- Need both? We can extract the Python client from the APK and use it inside the rebuilt feature.
Tell us what the app does and what you need from it.
Start a projectCommon questions
Which service do I need?
If you have an Android APK and need to call its API from your own code — choose APK to API. If you have a working feature somewhere and need it rebuilt into your codebase — choose Feature to Code.
Can a project use both services?
Yes. We can extract the APK's API into a Python client, then use that client while we rebuild the feature in your stack.
Do you need the original source code?
No. We work from running apps, APK files, test accounts, screen recordings, old binaries, partial documentation, or network captures. Source code speeds some projects up but is never required.
Do you work with companies outside Nigeria?
Yes. All work runs fully remote. Delivery, reviews, and handover can happen in any timezone.
What happens before work starts?
We scope the exact list of actions or features, agree on what success looks like, and write it down before we charge anything.
